The movie earned $6 million, which was considered a hit in 1966, and it received the "Boxoffice" magazine Blue Ribbon Award for the month of March that year.
In the movie, Suzanne Pleshette is obsessed with dachshunds, but in real life, she shared her home with a Yorkshire terrier named Missy. Because her pooch could smell Pleshette's "costars" on her when she got home at night -- and didn't like it -- the actress had to shower and change her clothes before leaving the studio.
Paul Frees completely looped the voice of character "Eddie", since actor Dick Wessel had passed away after the completion of principal photography.
